How do I make an abstract 3D waveform-deformed surface?
This can be done using a Displace modifier.




Add a sphere.
Add a Displace modifier.
Create a new texture for it.
Choose the texture type "Distorted noise" and play with the options to get something you like.
Copy the Displace modifier and change the Strength and Midlevel for more sharper edges.
Add a Subdivision Surface modifier and set type of subdivision to Catmull-Clark (default).
